Remember back in high school when you were learning to drive, and instructors foisted those grainy, 15-year-old video lessons on you like mushy porridge to prison inmates? Yeah, forget all of that—boring LaserDisc presentations just won’t cut it today, as proved by the National Highway Traffic Safety Administration’s latest anti-distracted-driving ad, which follows up the dry but critical distracted-driving guidelines with a harder-core moving-picture show.

The video opens on a typical scene of three teenagers in a car, laughing innocently, enjoying a sunny day, and jamming to music. But then the driver pulls out her phone and looks at it for a matter of seconds . . . during which she runs a stop sign. You can watch the video below to see what happens next, but let’s just say NHTSA isn’t playing softball.

But we’re glad the agency isn’t f@#$ing around—using your phone while driving a multiple-thousand-pound vehicle is so unbelievably stupid, and yet so seemingly acceptable to so many drivers, that the NHTSA could justifiably go even further. Say, maybe punish texting drivers by beating them over the head with mobile devices. Put down the phone, folks—seriously.
